This commit adds management functionality for connections and streams. BeBoB uses CMP to manage connections and uses AMDTP for streams. This commit also adds some BridgeCo's AV/C extension commands. There are some BridgeCo's AV/C extension commands but this commit just uses below commands to get device's capability and status: 1.Extended Plug Info commands - Plug Channel Position Specific Data - Plug Type Specific Data - Cluster(Section) Info Specific Data - Plug Input Specific Data 2.Extended Stream Format Information commands - Extended Stream Format Information Command - List Request For Extended Plug Info commands for Cluster Info Specific Data, I pick up 'section' instead of 'cluster' from document to prevent from misunderstanding because 'cluster' is also used in IEC 61883-6.

This commit adds two functionality for hwdep interface, adds two parameters for this driver, add a node for proc interface. To receive responses from devices, this driver already allocate own callback into initial memory space in host controller. This means no one can allocate its own callback to the address. So this driver must give a way for user applications to receive responses. This commit adds a functionality to receive responses via hwdep interface. The application can receive responses to read from this interface. To achieve this, this commit adds a buffer to queue responses. The default size of this buffer is 1024 bytes. This size can be changed to give preferrable size to 'resp_buf_size' parameter for this driver. The application should notice rest of space in this buffer because this driver don't push responses when this buffer has no space. Additionaly, this commit adds a functionality to transmit commands via hwdep interface. The application can transmit commands to write into this interface. I note that the application can transmit one command at once, but can receive as many responses as possible untill the user-buffer is full. When using these interfaces, the application must keep maximum number of sequence number in command within the number in firewire.h because this driver uses this number to distinguish the response is against the command by the application or this driver. Usually responses against commands which the application transmits are pushed into this buffer. But to enable 'resp_buf_debug' parameter for this driver, all responses are pushed into the buffer. When using this mode, I reccomend to expand the size of buffer. Finally this commit adds a new node into proc interface to output status of the buffer. Signed-off-by:

Fireworks firmware version 5.5 reports fix interval for dbc in each packet. For example, AudioFire4: CIP0 CIP1 Payload 00070000 900484FF 72 00070008 9004A8FF 72 00070008 90FFFFFF 02 00070010 9004D0FF 72 00070018 9004C4FF 72 00070020 9004E8FF 72 00070020 90FFFFFF 02 00070028 900410FE 72 The interval of each dbc should be 16 except for empty packet but it's still 8.

Fireworks has a quirk for the value of dbc field in transmitted packets. For Fireworks, dbc means the end of events in current packet. This is out of specification. For example, AudioFire4: CIP0 CIP1 Payload 01070092 90FFFFFF 02 0107009A 9001E17B 3A <- 010700A2 9001F6E5 3A 010700A2 90FFFFFF 02 010700AA 9001104F 3A <- 010700B2 900125B9 3A 010700BA 90013B23 3A 010700BA 90FFFFFF 02 010700C2 9001548E 3A <- 010700CA 900169F8 3A 010700CA 90FFFFFF 02 010700D2 90018362 3A <- 010700DA 900198CC 3A According to IEC 61883-1/6, a packet following to empty packet has the same value for its dbc. But for Fireworks, it's incremented and empty packet has the same value as previous packet in dbc field. This commit adds a flag for Fireworks and some codes to checking dbc continuity.

Fireworks manages connections by CMP and can transmit/receive AMDTP streams with a few quirks. This commit adds functionality to start/stop the streams. Major Fireworks products don't support 'SYT-Match' clock source mode, except for AudioFire12/8(till 2009 July) with firmware version 1.0. Already in previous commit, this driver don't support such old firmwares. So this commit adds support for non 'SYT-Match' clock source modes. I note that this driver has a short gap for MIDI streams when starting PCM stream. When AMDTP streams are running only for MIDI data and PCM data is going to be joined at different sampling rate, then AMDTP streams are stopped once and started again after changing sampling rate. Unfortunately, Fireworks is not fully compliant to IEC 61883-1/6. Some commits following to this commit add these quirks. Signed-off-by:

Fireworks uses own command and response. This commit adds functionality to transact and adds some commands required for sound card instance and kernel streaming. There are two ways to deliver substance of this transaction: 1.AV/C vendor dependent command for command/response 2.Async transaction to specific addresses for command/response By way 1, I confirm AudioFire12 cannot correctly response to some commands with firmware version 5.0 or later. This is also confirmed by FFADO. So this driver implement way 2. The address for response gives an issue. When this driver allocate own callback function into the address, then no one can allocate its own callback function. This situation is not good for applications in user-land. This issue is solved in later commit. I note there is a command to change the address for response if the device supports. But this driver uses default value. So users should not execute this command as long as hoping this driver works correctly. Signed-off-by:

This commit adds three commands, which may be used by some firewire device drivers. These commands are defined in 'AV/C Digital Interface Command Set General Specification Version 4.2 (2004006, 1394TA)'. 1. PLUG INFO command (clause 10.1) 2. INPUT PLUG SIGNAL FORMAT command (clause 10.10) 3. OUTPUT PLUG SIGNAL FORMAT command (clause 10.11) By the command 1, the drivers can get the number of plugs for AV/C unit or subunit. By the command 2 and 3, the drivers can get/set sampling frequency. The 'firewire-speakers' already uses INPUT PLUG SIGNAL FORMAT command to set sampling rate. So this commit also affects the driver.

Some devices based on BeBoB use this type of AV/C transaction. 'Deferred Transaction' is defined in 'AV/C Digital Interface Command Set General Specification' and is used by targets to make a response deferred during processing it. If a target may not be able to complete a command within 100msec since receiving the command, then the target shall return INTERIM response, to which final response will follow later. CONTROL/NOTIFY commands are allowed for deferred transaction. In the specification, devices allow to send INTERIM response just one time. But this commit allows to handle several INTERIM response with two reasons. One reason is to simplify codes, and another reason is to prepare for devices which is out of specification. There is an issue. In the specification, the interval between INTERIM response and final response is 'Unspecified interval'. The specification depends on each subunit specification for this interval. But we promise to finish this function for caller. In this reason, I use FCP_TIMEOUT_MS for this interval. Currently it's 125msec. When we find devices which needs more time for this interval, then let us add some codes to apply more interval for 'Unspecified interval'. Signed-off-by:

Plug Control Registers have two fields related to the number of established connections, one is 'Broadcast connection counter' and another is 'Point-to-point connection counter'. The driver can know there are established connections or not to check these fields. This commit is for considering about JACK/FFADO streaming. Currently, when JACK/FFADO starts its streaming to the device, cmp_connection_establish() is failed expectedly. This seems to be enough but there are some devices which needs to change sampling frequency before trying to establish connections. For such devices, this functionality is needed. Signed-off-by:

Currently, drivers can bring XRUN state for PCM substreams when error to queue packets or detecting discontinuity of packet. The application may try to recover this state by calling snd_pcm_prepare(). Depending on each driver, .prepare() includes restart streaming. Then there is a state that PCM substreams are running but isochronous contexts are stopped. In this case, when .pointer() is called, it refers to error pointer. This commit is for a prevention of this bug. Signed-off-by:

This commit adds common PCM constraints according to current firewire-lib implementation. 1.Maximum width for each sample is limited by 24. AM824 in IEC 61883-6 can deliver 24bit data. 2. Minimum time for period is 5msec. Apply the old value. For shorter latency, further works are needed. 3. In blocking mode, frames per period/buffer is aligned to 32. Each packet can include some frames depending on its sampling rate. In blocking mode, the number equals to SYT_INTERVAL. Currently firewire-lib can schedule snd_pcm_period_elapsed() for each packet. So, for accurate PCM interrupt, the number of frames per period/buffer should be aligned to SYT_INTERVAL. Currently firewire-lib is lack of better rules to achieve this. So LCM of each value of SYT_INTERVALs (=32) is applied. This can be improved for further work. [Fixed the compile error due to the missing "&" by tiwai] Signed-off-by:

Some devices arrange the position of PCM/MIDI data channel in AMDTP packet. This commit allows drivers to set channel mapping. To be simple, the mapping table is an array with fixed length. Then the number of channels for PCM is restricted by 64 channels. Signed-off-by:

Generally, the devices can synchronize to handle 'presentation timestamp' in CIP packets. This commit adds functionality to pick up this timestamp from in-packets transmitted by the device, then use it for out packets. In current implementation, this module generated the timestamp by itself. This is 'SYT Match' mode. Then drivers with this module acts as synchronization master. This commit allows this module to act as synchronization slave. This commit restricts this mechanism is only available in blocking mode because handling the timestamp in non-blocking mode is more complicated than in blocking mode. Signed-off-by:

For capturing/playbacking MIDI messages, this commit adds one MIDI conformant data channel. This data channel has multiplexed 8 MIDI data streams. So this data channel can transfer messages from/to 8 MIDI ports. And this commit allows to set PCM format even if AMDTP streams already start. I suppose the case that PCM substreams are going to be joined into AMDTP streams when AMDTP streams are already started for MIDI substreams. Each driver must count how many PCM/MIDI substreams use AMDTP streams to stop AMDTP streams. There are differences between specifications about MIDI conformant data. About the multiplexing, IEC 61883-6:2002, itself, has no information. It describes labels and bytes for MIDI messages and refers to MMA/AMEI RP-027 for 'successfull implementation'. MMA/AMEI RP-027 describes 8 MPX-MIDI data streams for one MIDI conformant data channel. IEC 61883-6:2005 adds 'sequence multiplexing' and apply this way and describe incompatibility between 2002 and 2005. So this commit applies IEC 61883-6:2005. When we find some devices compliant to IEC 61883-6:2002, then this difference should be handles as device quirk in additional work. About the number of bytes in an MIDI conformant data, IEC 61883-6:2002 describe 0,1,2,3 bytes. MMA/AMEI RP-027 describes 'MIDI1.0-1x-SPEED', 'MIDI1.0-2x-SPEED', 'MIDI1.0-3x-SPEED' modes and the maximum bytes for each mode corresponds to 1, 2, 3 bytes. The 'MIDI1.0-2x/3x-SPEED' modes are accompanied with 'negotiation procedure' and 'encapsulation details' but there is no specifications for them. So this commit implements 'MIDI1.0-1x-SPEED' mode for playback, but allows to pick up 1-3 bytes for capturing. Signed-off-by:
